Advantages of Circular Spiral Ducts

1. Adopting high-speed flying cutting machine, no burrs, no need for secondary processing, safe construction, high precision of pipe diameter.
2. The arc-shaped spiral pipe joint has better strength and airtightness than general circular pipes, and the inner joint of the pipe wall is smoother. It is suitable for air conditioning return air, fire protection air supply, etc.
3. CRIMPER (ripple type) joints are used for pipe ends below 200mm, without the need for flanges, for quick bonding and high air tightness.
4. Using SPIRORIB special reinforced spiral ducts is more economical and can save materials. Lightweight and easy to construct. Complete specifications, fast production speed, and prompt delivery.
